The explosion occurred in a small white bucket which was present inside the train.

Meanwhile, the police have declared the incident as a 'terrorist attack'.

Deputy Assistant Commissioner Neil Basu, the senior national coordinator for CT policing, has declared it as a terrorist incident, read the Metropolitan Police website.

Officers from the Met and British Transport Police attended the scene, along with colleagues from the London Fire Brigade and London Ambulance Service.

It is too early to confirm the cause of the fire, which will be subject to the investigation that is now underway by the Met's Counter Terrorism Command, read the Metropolitan Police website.

The station remains cordoned off and we are advising people to avoid the area.

I will be attending the emergency COBRA meeting in Whitehall this afternoon with the Prime Minister.My sincere gratitude goes to all our courageous emergency responders and the TfL staff who were first on the scene."
